INK-FEEDING ATTACHMENT FOR PENS.

Specification of Letters Patent.

Patented Nov. 28, 1916.

Application filed March 22, 1915. Serial No. 16,169.

To all whom it may concern Be it known that I, REINHOLD CEDARBOM, a citizen of the United States, and resident of the borough of Brooklyn, in the city and State of New York, have invented a new and useful Improvement in Ink-Feeding Attachments for Pens, of which the following is a specification.

y invention relates to an ink feeding attachment for pens with the object in view of providing a font which will hold a considerable quantity of ink and will feed it evenly to the pen.

Another object is to provide a device of this character which will be so located on the pen as not to interfere with its free use and which may be readily detached therefrom for cleaning.

A further object is to provide a font which can be formed from a blank of sheet metal or other suitable material, at a very little expense.

A practical embodiment of my inventlon is represented in the accompanying drawings, in which- Figure 1 represents a top plan view of a pen with my device attached thereto, Fig. 2 represents a vertical longitudinal section through the pen showing the manner of attaching my device thereto, Fig. 3 represents a bottom plan view of a pen with my device attached thereto, Fig. 4: represents a section taken in the plane of the line AA of Fig. 1, looking in the direction of the arrows, Fig. 5 represents a. view of the blank from which the font is formed, Fig. 6 represents an end view of my device unattached, Fig. 7 represents a side elevation of my device unattached, Fig. 8 represents a similar view to that shown in Fig. 6, showing the opposite end of my device, and Fig. 9 represents a bottom plan view of the device unattached.

The pen 1 may be of any one of the usual styles so long as it is provided with an elongated slot 2 extending lengthwise of the pen from the inner end of the slit leading to the nibs.

The font consists of three parts, viz; the reservoir 3, the connecting neck 4 and the feeding duct 5. The reservoir 3 is open ended and preferably cylindrical in shape, as shown in Fig. l, and the neck 4 is formed integral with the reservoir 3 and the wings 6 which form the feeding duct 5. These wings are spaced apart at one end and converge at their other end toward the nibs of the pen. The reservoir 3 is undercut, as shown at 7, and the wings 6 are tapered to points in the direction of the nibs of the pen, as shown in Fig. 2. This construction of the reservoir and wings permits the font to be readily attached to the pen and when the font is in operative position the reservoir 3 is located on the convex side of the pen, the neck A is in contact with the walls of the slot 2 and the feeding duct 5 is on the concave side of the pen. In order to hold the font in this position on the pen 1, the wings 6, which are made of resilient material, are spaced apart, adjacent to the neck 4:, a distance slightly greater than the width of the pen slot 2, so that after the wings have been pressed together to pass through the slot, they will spring back to their normal position, overlapping the edges of the slot, and thus hold the font in its proper position on the pen. I

I have found that my cylindrical reservoir will take up a considerable quantity of ink and distribute it as needed to the feeding duct, the novel construction of which insures an even and continuous feed to the pen nibs.

The font is formed from a blank of sheet metal or other suitable material, which has a central body portion adapted to be bent to form the reservoir, a pairof wings adapted to be bent to form feeding duct, and members, connecting the wings and the central body portion, which form a neck between the reservoir and duct.

It is evident that slight changes might be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of my invention; hence I do not wish to limit myself strictly to the structure herein set forth, but

What I claim is 1. A pen font blank comprising a central body portion and a pair of wings, the body portion being adapted to be bent to form an open ended reservoir and the wings to form a feeding duct.

2. A pen font blank comprising a central body portion and a pair of wings, the body portion being adapted to be bent to form an open ended reservoir and the wings to form V engage the pen to hold the parts in position.

3. A pen font blank comprising a' central body portion and a pair of Wings, the body portion being adapted to be bent to form a cylindrical open ended reservoir and the Wings to form a feeding duct.

In testimony, that I claim the foregoing as my invention, I have signed my name, this twentieth day of March 1915.

REINHOLD CEDARBOM.
